Improved Motion Segmentation Based on Shadow Detection
In this paper, we discuss common colour models for background subtraction and problems related to their utilisation are discussed. A novel approach to represent chrominance information more suitable for robust background modelling and shadow suppression is proposed. Our method relies on the ability to represent colours in terms of a 3D-polar coordinate system having saturation independent of th...

A novel approach to represent chrominance information more suitable for robust background modelling and shadow suppression is proposed.

متن کاملShadow Detection based on Colour Segmentation and Estimated Illumination
In this paper we show how to improve the detection of shadows in natural scenes using a novel combination of colour and illumination features. Detecting shadows is useful because they provide information about both light sources and the shapes of objects thereby illuminated. Recent shadow detection methods use supervised machine learning techniques with input from colour and texture features ex...
متن کاملMotion-Segmentation-Based Change Detection
Detecting regions of change in images of the same scene taken at different times is of widespread interest. Important applications of change detection include video surveillance, remote sensing, medical diagnosis and treatment. Change detection usually involves image registration, which is aimed at removing meaningless changes caused by camera motion. Image registration is a hard problem due to...
متن کاملImproved Shadow Removal for Unstructured Road Detection
One of the greatest challenges for vision-based road detection is the presence of shadows and other vehicles. It’s particularly challenging to detect unstructured road when it has both shadowed and non shadowed area since the presence of shadows can cause hindrance and shape distortion of objects which may result in false detection of road. Shadows can also cause a significant problem in road d...
